A child who weighs 55 pounds receives a prescription for cefotaxime 150 mg/kg/day intravenously in divided doses every 6 hours.
How many mg should the nurse administer each day?

The correct answer is choice C: Increase rate of ventilation.

Choice A rationale:

Decreasing expiratory flow time would not directly address the elevated PaCO2 levels. This intervention is more related to managing expiratory phase issues rather than correcting respiratory acidosis.

Choice B rationale:

Decreasing expiratory pressure might help with certain ventilation issues, but it does not specifically target the elevated PaCO2 and resulting acidosis.

Choice C rationale:

Increasing the rate of ventilation helps to blow off more CO2, thereby reducing PaCO2 levels and correcting the respiratory acidosis indicated by the pH of 7.26 and PaCO2 of 68 mm Hg.

Choice D rationale:

Increasing the ventilator tidal volume could also help reduce PaCO2 by increasing the amount of air exchanged with each breath. However, increasing the rate of ventilation is generally a more immediate and effective intervention for acute respiratory acidosis.

Choice B rationale:

Stroke is a condition that occurs when the blood supply to a part of the brain is interrupted, causing brain tissue damage. Facial drooping and garbled speech are common signs of stroke, especially if they occur suddenly and on one side of the face.Stroke is a medical emergency that requires immediate treatment to prevent further brain damage and complications

Choice C rationale:

An allergic reaction could cause various symptoms, but it typically does not result in facial drooping or garbled speech. Common signs of an allergic reaction include hives, itching, redness, and swelling of the skin, as well as difficulty breathing in severe cases (anaphylaxis). There is no mention of these symptoms in the client’s presentation.

Choice D rationale:

Malignant hypertension is a possibility given the client’s extremely high blood pressure reading. This condition refers to severe hypertension that can quickly lead to organ damage. However, while it can cause neurological symptoms if it leads to a hypertensive crisis, the specific symptoms of facial drooping and garbled speech are more indicative of a stroke. In conclusion, based on the collected data, the nurse recognizes that the client is most likely exhibiting signs of a stroke as evidenced by neurological defects (facial drooping and garbled speech). The client’s high blood pressure and reported alcohol consumption are both risk factors for stroke. Immediate medical intervention is crucial to minimize brain damage and potential complications.
